Fig. 6 explains the RFID reader, the example of coupling between main label 4B and the markup tags 6.In Fig. 6, main antenna 62 and slave antenna 40B can form individual module (for example, Fig. 5 70) in an encapsulation, perhaps can be disparate modules.RFID reader antenna 52, the main antenna 62 of main label 4B and the slave antenna 40B of main label 4B respond to coupling closely, so that any energy or data-signal of launching from an antenna all will be received by other antennas.In this example, the ID of main label 4B representes a group echo label 6.
Markup tags 6 is communicated by letter with main label 4B through the 8A of wired connection system.Slave antenna 30 electricity of the slave antenna 40B of main label 4B and markup tags 6 are led coupling.
In Fig. 6, show two markup tags 6.Yet the quantity of markup tags 6 is not limited to two, can be according to maybe needs change of system design.In Fig. 6, show a main label 4B.Yet the quantity of main label 4B is not limited to one, can be according to maybe needs change of system design.System can comprise a plurality of main label 4B, and the ID of each main label 4B can represent 6 groups on different markers label.
When RFID reader 50 output RF signals, because near, main antenna 62 all receives the RF signal with slave antenna 40B.RFID reader 50 is as transmitter, and two antenna 40B among the main label 4B and 62 are as receiver or two-pack antenna.Be similar to transformer with three coil antennas.
When markup tags 6 activates through the 8A of wired connection system (electricity is led coupling), any coding that reads from markup tags 6 all will be transferred to the slave antenna 40B of main label 4B through the 8A of wired connection system.Slave antenna 40B is coupled to main antenna 62 and RFID reader 52.Therefore, RFID reader 50 receives the information that reads from markup tags 6.RFID reader 6 can receive the information that reads from the label model of main label 4B (60).
50 whiles of RFID reader communicate by letter with slave antenna 40B with the main antenna 62 among the main label 4B.After this, balance, the for example direct distance of its coil dimension and coil are depended in the coupling between these antenna how much.RFID reader 50 can between or indirectly with slave antenna 40B, main antenna 62 or its combined communication.
Main antenna 62 can be big coil.In this example, big coil (main antenna) 62 grasps the energy that RFID reader 50 produces, and then it is transferred to slave antenna 40B.Because artificial/actual cause, the distance between RFID reader antenna 52 and the main antenna 62, the perhaps distance between RFID reader antenna 52 and the slave antenna 40B can be greater than the distance between main antenna 62 and the slave antenna 40.
In Fig. 6, markup tags 6 uses main label 4B, and 8A communicates by letter with RFID reader 50 through wire cable (electricity is led coupling).Yet markup tags 6 can directly be communicated by letter with RFID reader 50.In Fig. 6, main label 4B is connected to markup tags 6 through terminal box 14A.Yet main label 4B can be directly connected to markup tags 6.
With reference to Fig. 1, system 2 uses multipoint access function simultaneously, is called the impact algorithm of many tag operational.This label impact function can be implemented in the tag/reader agreement, and this agreement allows to use the time separating system, successively to all label addressing.For instance, system 2 can adopt the pairing impact mechanism of standard ISO 15693-3.
The RFID reader (for example, Fig. 4,6 and 8 50) have a RFID label protocol, how definition how reads ID to the specific label addressing, perhaps how to read the particular memory block of specific label.All above-mentioned agreements all are the parts of standard label agreement.All labels all activate, yet, can realize selectivity read/write to particular address.
